Abstract

Quinolines are important herbicides and are used widely but their acetic acids function is still detectable that might have some prominent effects on seed germination and growth of plantlets. A series of 2-methylquinolin-4(1H)-on-3-acetic acids have been synthesized from substituted anilines. These compounds were subjected to evaluate their biological action on wheat (Triticum aestivum) and sorghum (Sorghum bicolor) seeds germination along with early growth of seedlings. At high concentrations these compounds were proved to have inhibitory effect on root and shoot growth both in sorghum and wheat. While at low concentration these compounds were found to have stimulatory effect on sorghum but inhibitory effect on wheat growth. Quinolin-4(1H)-on-3-acetic acids is supposed to delay the germination of seeds simply by lowering the metabolic process during the imbibitions.
